TONGS.

Application filed March 11, 1921.

To all whom it may concern:

Be it known that I, MroHAnL RosnI-rrLL, a citizen of the Dominion of Canada, residing at Lobley, in the county of Calgary and Province of Alberta, Canada, have invented certain new and useful Improvements in Tongs, of which the following is a specification.

This invention relates to improvements in blacksmiths tongs, and the objects of the invention are to construct the tongs so that they will be adjustable and thus able to be used to grip small or large pieces of iron or other work before being performed by the blacksmith, and to render the tongs strong and durable, yet light and easily handled.

These tongs are also intended to cut down the expense by enabling one pair of tongs to perform work which usually requires a large range of tongs to handle, it also eliminates the liabiliy of the tongs being lost, because there will only be one pair where previously there would be many pairs for the same class of work.

So that the nature of my invention will be properly understood, I have illustrated a preferred embodiment of the same, which I will now describe in detail, after which the novel features will be pointed out in the ap ended claims.

11 the drawings: Figure 1 is a side elevation of the improved tongs when closed, the dotted lines indicating the position of the levers and jaws when open.

Figure 2 is a side elevation of my improved tongs with the jaws open to a larger extent than indicated in Figure 1.

Figure 3 is a side elevation of the movable Jaw.

Figure 4 is a perspective view of the jaw which is formed integral with one of the levers.

Figure 5 is an end view of the jaw shown in Figure 4 with the movable jaw shown in Figure 3 mounted therein.

Figure 6 is a perspective View of the end of the lever which is designed to be adj ustably connected to the aw illustrated in Figure 3. Like symbols of reference indicate corresponding parts throughout the drawin s.

eferring to the drawings, the improved tongs consist of two levers 1 and 2, the former Specification of Letters Patent.

of which is provided intermediate ofv its length wlth a knife edge 3, and the latter is provided with a projection 4 with which the.

knife edge engages.

The two levers are connected by side plates 5, the hinge pins of which extend through the levers. The lever 52 is formed integral with the jaw 6 which is provided with a rectangular orifice 7 through the body thereof and a rectangular groove 8 in the lower wall of the said orifice.

The orifice 7 is open on its upper face. for part of'its length and is provided with .a rectangular shoulder 9. i

The face 10 of the jaw whichengages with i the work to be held by the tongues has a longitudinal recess 11 therein and the body of the jaw has elliptical openings 12 through the side walls.

The lower wall of the jaw 6 adjacent to the lever 2 is formed with a rectangular opening 13 therein. The movable jaw 14 has a shank 15 arranged at right angles thereto, and provided with a longitudinal recess 16 in one side thereof and a tongue 17 depending from the shank 15, and this tongue has a plurality of holes 18 therethrough.

The shank 15 is rectangular and slidably engages with the rectangular orifice 7 in the fixed jaw and the longitudinal recess 16 en- 7 gages with the rectangular shoulder 9.

The upper end of the lever 1 is bifurcated as shown at 19 and engages with thetongue 17, the said bifurcated end being slidable in the orifice 13. A screw 20 passes through orifices in the bifurcated end 19 of the lever 1, and through a registering orifice 18 in the tongue 17 of the movable jaw.

The movable jaw is also provided on its gripping face with a recess 21.

When the tongs are in use, the shank of the slidable jaw engages with the' rectangular orifice 7 in the fixed jaw with the tongue 17 engagingthe recess 8, and the recess 16 en aging the shoulder 9.

he upper end of the leverl is now inserted into the opening 13 of the fixed jaw, and the screw 20 passed through the registering orifices in the bifurcated end 19 of the lever, and the orifice 18 in the tongue 17 which the said bifurcated end embraces.

The levers 1 and 2 form hand grips and when the ends of the lever are spread apart the jaws will also be spread apart, and when the work has been gripped between the jaws,

the levers 1 and 2 are pressed together to tighten the jaws on the said work.

The knife edge 3 forms a fulcrum on the projection 5 around which the levers 1 and 2 are rotated and insures ease of movement.

If the jaws have to be adjusted to take in wqrl; of a larger or smaller size, then the screw 20 is removed and engages with one of the outer orifices 18 or one of the inner orifices 18 after being entered into the bifurcated end 19 of the lever 1. j

This would spread the 'aws or bring them nearer so that they would take heavier or lighter work.

The tongs are light, strong and form a very handy tool which is always ready for use. a

,What I claim as my invention is:

, 1-. A. pair of tongs comprising a pair of levers having a knife edge fulcrum, a jaw formed integral with one" of the levers and having a guide opening therethrough, a

movable jaw having a shank slidably engaging the said guide opening, i a lever,

, means for connecting the lever to the movthe levers together adjacent to the knife edge and projection, a jaw integral with one of the levers, a movable jaw slidably mounted in the fixed jaw, and means connecting the movable jaw to the second lever.

3. A pair of tongs comprising a pair of levers, pivotally connected intermediate of their length and having a knife edge fulcrum, a fixed jaw integral with one of the levers, a movable jaw having a shank slidably engaging the fixed jaw, and adjustable means connecting the second lever to the shank of the movable jaw, whereby the openings of the jaws may be adjusted, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
